Definitions
- the present invention belongs to the technical field of tobacco processing. More specifically, the present invention relates to a heat-not-burn cartridge having a dual structure.
- the heat-not-burn product is a new type of product developed in recent years, and due to the fact that the external heat source is used for heating and baking to release the smoke, the harmful ingredient release amount of the product is remarkably reduced, and compared with traditional smoke tobacco, the safety of the product is remarkably improved.
- the heat-not-burn tobacco product has the characteristics and advantages of rich taste, no sidestream smoke, no soot pollution and the like, and has been accepted in the market, and good market feedback has been achieved.
- the annual sales scale of products such as iQOS produced by Philip Morris International, Glo produced by British American Tobacco, Ploom produced by Japanese tobacco, lil produced by Korean tobacco, has exceeded 200 million boxes per year, occupying more than 3% of market share of foreign tobacco market.
- the heat-not-burn product usually adopts a multi-structure composite filter rod to regulate and control the concentration and temperature of the smoke, it cannot effectively solve the problem due to the technical problems of related material selection and structural design.
- the total smoke particle phase per cigarette for the generally heat-not-burn product is not higher than 18mg, and the temperature of the smoke and the surface temperature of the filter tip are higher than 45°C.
- the complex filter rod structure results in difficult manufacturing and high cost.
- US 20140305448 A1 titled "Aerosol-generating article for use with an aerosol-generating device” disclosed a heat-not-burn cartridge having a four-membered structure, which is a smoke formation section, a supporting section, a cooling section and a filtering section, respectively.
- the production process is complex, the cooling section can be melted in the suction process, thus affecting the smoking experience. It exist the defects of small smoke amount, high smoke temperature and the like;
- CN 110680018 A the titled "A support for an incense core and an incense core having the same”
- an embodiment disclosed a heat-not-burn cartridge structure of a ternary structure, which is a smoke formation section , a high-temperature-resistant smoke channel section and a filter section, respectively.
- the smoke cartridge production process is simplified, the smoke temperature is reduced to a certain extent, but the smoke amount of the filter section is lower, and the pain point with high smoke concentration is not solved.
- the heat-not-burn cigarette comprises a matrix section, a smoke collection section circulation element and an external wrapping element, wherein the matrix section comprises an smoke formation section and a smoke passing section.
- the smoke passing section a part of fragrance and smoke are adsorbed, so that the aroma release is influenced, and the smoke concentration is reduced;
- the smoke collection section is composed of one or more of an acetate fiber tube, a polylactic acid tube and a paper tube, and the cooling effect of the selected material of the smoke collection section in practical application is not obvious.
- a utility model titled"Composite smoke circulation rod, smoke circulation product and smoke circulation system” disclosed a heat-not-burn product having composite smoke circulation section, it is composed of a composite smoke circulation section and a smoke formation section, wherein the composite smoke section is two cylinders having through holes, they are made by cellulose acetate tow or polylactic acid tow material. From the effect of the embodiment, the smoke concentration has increased to a certain extent, but smoke temperature is above 42°C. It solved the problem of smoke concentration, but the problem of high smoke temperature has not been solved.
- the present inventors have completed the present invention by analyzing and summarizing the prior art and performing a large number of tests and analysis.
- An object of the present invention is to provide a heat-not-burn cartridge having a dual structure.
- the present invention is achieved by the following technical solutions.
- the present invention relates to a heat-not-burn cartridge having a dual structure.
